Smart lock battery draining fast
4.5
Batteries that should last 6 months are dying in a few weeks.
Symptoms
- Low battery alerts
- Slow operation
- Frequent replacements
Possible Causes
- Friction in bolt
- WiFi searching
- Cold weather
Step-by-Step Fix
1
Reduce Friction
Sand the strike plate hole so the bolt slides with ZERO resistance.
2
Use WiFi Bridge
If the lock uses WiFi directly, it drains faster. Use a Bluetooth-to-WiFi bridge.
3
Use Lithium Batteries
Lithium AA batteries last much longer in smart locks than alkaline.
When to See a Technician
The motor works hardest when it has to "push" against a misaligned door, which kills the battery quickly.
